ELIVOOD C. PHILLIPS, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-FOURTH TO OSCAR A. SCHEIBE, OF CHICAGO, ILLINOIS.

CULINARY (SHOPPING-KNIFE.

SPECIFICATION forming part of Letters Eatent No. 697,167, dated April 8, 1902. Application filed August 23,1900. Serial No. 27,845. (No model.)

To (LZZ whom, it may concern:

Be it known that I, ELWooD G. PHILLIPS, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Culinary Chopping-Knives, of which the following is a specification.

The present invention relates to that class of culinary chopping-knives having a segmental cutting edge and which are adapted for use in a concaved wooden disk in cutting slaw and like material in preparation of the same for household food.

The object of the present improvement is to provide a simple and effective construe tion of the cutting-blade of a culinary chopping-knife, by means of which the chopping action is materially increased and great stiffness and rigidity imparted to the cuttingblade, all as will hereinafter more fully appear and be more particularly pointed out in the claim. I attain such objects by the construction and formation of parts illustrated in the accompanying drawings, in which- Figure lis a side elevation of a culinary.

chopping-knife embodying the present invention; Fig. 2, a plan View of the blade of the present invention with the handle removed; Fig. 3,a transverse section of the same.

Similar numerals of reference indicate like parts in the different views.

Referring the drawings, 1 represents the cutting-blade, having the usual segmental form, and which blade in the present invention is formed with a series of corrugations 2, that are radially arranged with relation to a common center, as illustrated in Fig. 1.

In the manufacture of the present blade the same will be formed from a fiat sheet of steel corrugated in the manner shown and with the corrugations at top of greater depth than those at the bottom of the blade, and as so formed the present improved cutter or blade will be of a downwardly-tapering form, as illustrated in Fig. 3,and as so constructed a blade possessing great stiffness and rigidity is provided. 0

3 is the handle, of a hasp form, with its dependent attaching legs or members 4 attached to the corrugated cutter-blade 1 near the opposite ends of the same and as so attached imparts added strength and stiffness to the corrugated cutter-blade 1 of the present in-' vention.

With the present improved construction a culinary chopper can be provided having increased cutting capacity and ample stiffness and rigidity combined with extreme lightness.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

A culinary chopping-knife, comprising a handle, and a cutting-blade having a segmental shape and formed with vertically-extending corrugations that taper away from the cutting edge of the blade and have a radial arrangement with relation to a common center, substantially as set forth.

Signed at Chicago this 18th day of August, 1900.
